Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and specifically to a front-maintenance LED display module that is easy to maintain. Background Technology

[0002] With the rapid development of technology, LED display technology has the advantages of high brightness, high contrast, energy saving and environmental protection. Compared with traditional display devices, it has lower energy consumption, which can effectively reduce the cost of use and reduce the impact on the environment. It has been widely used in many display fields. Front-maintenance LED display modules have received widespread attention from the market due to their unique installation and maintenance methods. Compared with traditional rear-maintenance LED display modules, front-maintenance LED display modules allow maintenance operations to be performed from the front of the display screen without disassembling the entire display screen or reserving a large rear space, which greatly saves installation space and maintenance costs. It is especially suitable for places with limited space or complex installation environments.

[0003] However, existing front-maintenance LED display modules are usually fixed with multiple screws or clips. The screw fixing method requires the use of special screwdrivers and other tools to unscrew each screw in order to disassemble the component. During the disassembly process, due to the large number of screws and their distribution in different locations, the operation is cumbersome and time-consuming, which brings a lot of inconvenience to the installation and disassembly work. Utility Model Content

[0004] The purpose of this utility model is to provide a front-maintenance LED display module that is easy to maintain, in order to solve the problems of existing front-maintenance LED display modules having a large number of screws distributed in different positions, which makes operation cumbersome, time-consuming, and causes a lot of inconvenience to installation and disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a front-maintenance LED display module that is easy to maintain, comprising:

[0006] The base mechanism and the LED display module mechanism assembled at the front end of the base mechanism, and the locking mechanism assembled at the rear end of the LED display module mechanism;

[0007] The base mechanism includes a fixed frame, the fixed frame has an installation cavity inside, and the four corners of the installation cavity have locking grooves.

[0008] The LED display module mechanism includes a base plate that abuts against the front end of the fixed frame, and an LED display screen is mounted on the front end of the base plate;

[0009] The locking mechanism includes a fixed box fixedly installed at the rear end of the substrate. A gear is rotatably installed inside the fixed box. A drive frame meshes with the top and bottom of the gear. A conical block is fixedly connected to one side of the drive frame via a moving rod. A locking post is slidably installed at the top and bottom of the conical block. One end of the locking post extends into the locking groove.

[0010] Furthermore, the surface of the LED display screen is provided with a front maintenance hole, and the inside of the gear is provided with an internal hexagonal hole that communicates with the front maintenance hole.

[0011] Furthermore, a guide opening is provided at the entrance of the locking groove, and the guide opening is horn-shaped.

[0012] Furthermore, the inner wall of the drive frame is fixedly equipped with teeth that mesh with the gear, and the drive frame and the fixed box are connected by a sliding rod with a sliding hole.

[0013] Furthermore, the locking stake and the conical block are slidably installed together by a slider, and the top and bottom of the conical block are fixedly equipped with sliding frames for the slider to slide.

[0014] Furthermore, the locking stake is slidably mounted to the base plate via a first sliding sleeve, and the moving rod is slidably mounted to the base plate via a second sliding sleeve. The inner wall of the second sliding sleeve is fitted with a rubber pad that fits against the moving rod.

[0015] Compared with existing technologies, this utility model provides a front-maintenance LED display module that is easy to maintain. By setting a locking mechanism, only a hex wrench needs to be inserted into the gear at the front end of the LED display module. Rotating the gear drives the two drive frames to move relative to each other, which can drive the conical block to move left and right. Utilizing the inclined action of the conical block, the four locking posts can be pushed simultaneously to perform tilting and telescopic movements, so that the four locking posts can simultaneously engage with the locking slots at the four corners of the mounting cavity to complete the locking operation. At the same time, the four locking posts can be simultaneously pulled out of the locking slots to complete the disassembly. Locking and unlocking operations can be completed with one button, which can effectively reduce the operation steps and reduce the operation time, and enable quick installation and disassembly of the LED display module mechanism.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] Example 1:

[0028] This utility model provides a front-maintenance LED display module that is easy to maintain, including:

[0029] The base mechanism 1, the LED display module mechanism 2 assembled at the front end of the base mechanism 1, and the locking mechanism 3 assembled at the rear end of the LED display module mechanism 2;

[0030] The base mechanism 1 includes a fixed frame 11, the fixed frame 11 has an installation cavity 12 inside, and the four corners of the installation cavity 12 have locking grooves 13.

[0031] The LED display module mechanism 2 includes a substrate 21 that abuts against the front end of the fixing frame 11, and an LED display screen 22 is mounted on the front end of the substrate 21.

[0032] The locking mechanism 3 includes a fixing box 31 fixedly installed at the rear end of the base plate 21. A gear 39 is rotatably installed inside the fixing box 31. A drive frame 32 meshes with the top and bottom of the gear 39. A conical block 34 is fixedly connected to one side of the drive frame 32 via a moving rod 33. A locking post 35 is slidably installed at the top and bottom of the conical block 34. One end of the locking post 35 extends into the locking groove 13.

[0033] As can be seen from the above, when using the LED display screen 22, by inserting a hex wrench into the gear 39 from the front end, the gear 39 can be rotated, which in turn drives the upper and lower drive frames 32 to slide into the fixed box 31. The drive frames 32 can pull the moving rod 33 to move, and the moving rod 33 can drive the conical block 34 to move synchronously. By using the movement of the conical block 34, the locking stake 35 can slide along the slope of the conical block 34, allowing the locking stake 35 to move in an inclined telescopic motion. All four locking stakes 35 can be pulled out from the locking groove 13 at the same time, completing the unlocking operation in one go. This allows the LED display module mechanism 2 to be disassembled from the front end of the fixed frame 11, facilitating front maintenance operations.

[0034] During installation, the substrate 21 is attached to the fixing frame 11, allowing the locking mechanism 3 to extend into the mounting cavity 12. By inserting a hex wrench into the gear 39 from the front end of the LED display 22, the gear 39 is rotated in the opposite direction. The gear 39 can then move the two drive frames 32 to the sides of the fixing box 31. The moving rod 33 can push the cone blocks 34 distributed on the left and right sides to move to the sides. The slope of the top and bottom of the cone blocks 34 can press the four locking pins 35, allowing them to be simultaneously reinserted into the locking slots 13. This allows for a quick locking operation, effectively reducing the number of steps and the time required for operation. It also enables the rapid installation and disassembly of the LED display module mechanism 2.

[0035] From the appendix Figure 3 and attached Figure 5 It can be seen that the surface of the LED display screen 22 is provided with a front maintenance hole 23, and the inside of the gear 39 is provided with an internal hexagonal hole 312 that communicates with the front maintenance hole 23.

[0036] As can be seen from the above, the position of the front maintenance hole 23 between the LED beads on the LED display screen 22 does not affect the display effect of the LED display screen 22. By inserting a hex wrench into the front maintenance hole 23, the hex wrench can be extended into the internal hexagonal hole 312 inside the gear 39. Through the limiting effect of the internal hexagonal hole 312 on the hex wrench, the gear 39 can be rotated by rotating the hex wrench. The locking and unlocking operations can be easily completed through only one operating position.

[0037] For details, please refer to the appendix. Figure 2 As shown, a guide opening 14 is provided at the entrance of the locking groove 13, and the guide opening 14 is in the shape of a horn.

[0038] As can be seen from the above, the funnel-shaped guide port 14 can provide a positioning function for the locking stake 35, so that when the locking stake 35 touches the slope position of the guide port 14, it can be smoothly guided into the locking groove 13, which can quickly align and avoid the situation where the locking fails due to misalignment.

[0039] For details, please refer to the appendix. Figure 5 As shown, the inner wall of the drive frame 32 is fixedly installed with teeth 311 that mesh with the gear 39, and the drive frame 32 and the fixed box 31 are connected by a sliding rod through a sliding hole 314.

[0040] As can be seen from the above, through the meshing action of the teeth 311 and the gear 39, the gear 39 can rotate and drive the drive frame 32 to move. Through the limiting effect of the sliding hole 314 on the drive frame 32, the drive frame 32 can remain stable during the sliding process and is not prone to shaking or tilting.

[0041] Working principle: By inserting a hex wrench into the gear 39 through the front maintenance hole 23, the gear 39 can be rotated. The gear 39 can drive the two drive frames 32 to extend outward from the fixed box 31. The moving rod 33 can push the conical blocks 34 distributed on the left and right to move synchronously. The conical blocks 34 can simultaneously exert a squeezing effect on the four locking pins 35, allowing the four locking pins 35 to move in an inclined direction. The four locking pins 35 can be simultaneously inserted into the locking slots 13 at the four corners of the mounting cavity 12 to complete the locking operation. By driving the gear 39 to rotate in the opposite direction with the hex wrench, the drive frame 32 can be retracted into the fixed box 31. The moving rod 33 can synchronously drive the conical blocks 34 to reset, allowing the four locking pins 35 to be simultaneously pulled out from the locking slots 13, quickly completing the unlocking operation.

[0042] Example 2:

[0043] Reference Appendix Figure 6As shown, the locking post 35 and the conical block 34 are slidably installed together by a slider 313, and the top and bottom of the conical block 34 are fixedly installed with sliding brackets 38 for the slider 313 to slide.

[0044] As can be seen from the above, by limiting the slider 313 through the sliding frame 38, the locking post 35 and the conical block 34 will not fall off. When the conical block 34 squeezes the locking post 35, the slider 313 can slide along the sliding frame 38, and the locking post 35 can move in and out with the movement of the conical block 34.

[0045] Reference Appendix Figure 5 and attached Figure 6 As shown, the locking post 35 is slidably installed with the base plate 21 via the first sliding sleeve 36, and the moving rod 33 is slidably installed with the base plate 21 via the second sliding sleeve 37. The inner wall of the second sliding sleeve 37 is fitted with a rubber pad 310 that fits against the moving rod 33.

[0046] As can be seen from the above, the first sliding sleeve 36 can limit the tilt angle of the locking post 35, allowing the locking post 35 to slide in an inclined manner along the first sliding sleeve 36. The second sliding sleeve 37 allows the moving rod 33 to slide horizontally. The friction generated when the rubber pad 310 contacts the moving rod 33 can dampen and fix the moving rod 33, fixing it after the moving rod 33 moves. This makes it less likely for the locking post 35 to fall out when inserted into the locking groove 13, bringing more convenience to the user.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
